Why are glycols so effective?
They are very effective in heating applications due to several properties, such as: High specific heat capacity. High thermal conductivity. Low viscosity. Water miscibility. Water and glycol solutions present many benefits for industrial processes, on the other hand, these are not the only heat transfer mediums available.
Is glycol a heat transfer medium?
Water and glycol solutions present many benefits for industrial processes, on the other hand, these are not the only heat transfer mediums available. Synthetic and organic thermal oils are also sometimes selected as they work well in temperatures up to 750° F and produce very little vapor pressure. Water without additives can also be used, although within more limited conditions due to its low-temperature intolerance and boiling point. It is also possible for water to produce a dangerous amount of vapor pressure at certain temperatures.
Is Water Quality That Important?
Some HVAC specialists take water quality for granted. However, it can and does play an important role in ensuring problem-free operation of hydronic heating systems. Trace deposits of metals and other contaminants can produce sludge that blocks components of the hydronic system and reduces its efficiency. Over time, sediment deposits damage the system and deplete a system’s corrosion inhibitors creating the perfect conditions for internal corrosion and eventually shortening the life of the system.
How long does X500 glycol last?
While most non-inhibited glycol products have a three to five-year lifespan, pre-mixed Sentinel X500 glycol can provide up to 20 years of service before needing replacement. Pre-mixed Sentinel glycol uses pure, neutral-pH water which is an important life-extending factor, since “heavy/hard water” contains trace metals and other mineral impurities which shorten glycol life spans and corrode hydronic pumps, boilers, valves, and fittings.
What is X500 glycol?
Sentinel X500 Glycol is a propylene-based glycol compound that contains a unique blend of corrosion-inhibiting chemicals. These additives prevent system degradation, significantly extending the life expectancy of hydronic heating appliances and the glycol used in the system.
What is glycol used for in heating?
Using Glycol in Hydronic Heating Systems. Glycol, also called antifreeze, is an important compound that HVAC manufacturers use to protect hydronic heat ing systems in cold climates. When added to water, glycol lowers the freezing temperature of the resulting mixture, ensuring that it remains liquid even during harsh winter weather.
What is the best antifreezing agent for HVAC?
Ethylene glycol. A historically popular and very effective anti-freezing agent, modern HVAC experts try to avoid using ethylene glycol because of its toxicity. Nonetheless, it is commonly implemented in industrial settings where strict regulation prevents any chance of it seeping into drinking water. Propylene Glycol.
Does glycol help with HVAC?
For this reason, HVAC system designers must pay close attention to the minimum temperature they expect any particular system to encounter. The amount of glycol incorporated into the system should ideally prevent freezing at that temperature without exceeding concentration parameters – this ensures the best possible performance.
Is glycol better than water?
Glycol has a higher viscosity and lower heat transfer characteristics than water. For this reason, HVAC engineers typically dilute glycol with water inside hydronic heating systems. The maximum recommended ratio for glycol dilution with water is 1:2. A glycol concentration lower than 50% avoids overtaxing the performance of the system’s boilers and pumps while eliminating the risk of damage occurring in low-temperature climates.
What is the best tool to measure glycol concentration?
On-Site Glycol Fluid Analysis. We recommend self-testing using an on-site fluid analysis tool such as a refractometer monthly. A refractometer test measures the glycol concentration and gives the glycol freezing point of your solution. This instrument requires only a few drops of fluid for testing and requires no adjustment for fluid temperature. Need to increase your system's concentration (also known as correcting glycol concentration or balancing glycol concentration)? Use our easy concentration correction calculator to find out how much glycol is needed.
What is the pH of glycol?
Testing Your Glycol pH Level. Control of glycol pH level between 8.0 and 10.0 is important to minimize corrosion and glycol degradation. Using narrow range pH paper is an easy and reliable way to read your pH level. A pH tester can also measure alkalinity or acidity of the fluid. Any fluid with a pH below 7.0 should be replaced. For fluids between 7.0 and 8.0 adjustments can be made using a 50% solution of sodium hydroxide or potassium hydroxide.
How to tell if fluid needs replacement?
Examine your fluid for appearance and odor. Any drastic variation from the initial fluid specifications such as black or dark-gray color, presence of an oily layer, burnt odor or any heavy sludge in the fluid may indicate the need for fluid replacement. Contact us today if you notice any of these signs in your system solution.

How do electronic cigarettes work?
All e-cigarettes operate on a simple principle: A liquid is converted to a vapor through the process of heating it. A battery sends an electric current to a wad of liquid-soaked wicking material that is tightly wrapped with a metal coil that heats up like a burner on an electric stove. Once the coil becomes hot enough, the liquid that is in contact with the coil also begins to heat up, eventually to the point the liquid becomes converted to a vapor, which is then inhaled. The liquid that turns to vapor is propylene glycol, which contributes to taste and “smoothness” of the smoke.
